Model describing the effect of CUL5 on the sensitivity of bladder cancer cells to CD8+ T cell-mediated killing. CUL5-KO could reduce the ubiquitination of PTBP1, thereby increasing the alternative splicing of RUBCN pre-mRNA, leading to an increase in Rubicon-S which inhibits autophagy, and thus enhances the sensitivity of bladder cancer cells to CD8+ T cell-mediated killing (cartoon created in BioRender).
